Merge tag 'sound-4.16-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound 

Pull sound fixes from Takashi Iwai:
 "Things look calming down, but people were still busy to plaster over
  small holes:

   - Two fixes to harden against races in aloop driver

   - A correction of a long-standing bug in USB-audio UAC2 processing
     unit parser

   - As usual suspects, HD-audio: a workaround for Coffee Lake
     controller and a few other device-specific fixes

  All small and for stable"
